' To all whom it may concern:

Be it known that I, zen of the United States, ford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Couplings, of which the following is. at specification. 7

his invention relates to couplings, one of the primary objects of the invention being to provide an article of this character byof relatively separable which a plurality members can be detachably connected and which when in active position effectively maintains said members in proper relation with each other, the construction being such that the coupling can be readily and quickly applied and as easily'removed.

At the outset I desire to make it clear that the coupling can be employed with facility in widely-different connections, although it is of peculiar advantage when used in the being adapted when utilized in this particular connection for connecting a shade, globe or guardwith an" incandescent lamp socket, these being merely three of the many examples.

In the drawings accompanying and form-- ing part ofthe present specification I have shown several of the many different forms of embodiment of'the invention which Wlll f 'be set forth in detail in the following description. It will be obvious that I do not restrict myself to this particular disclosure; I may depart therefrom in several respects within the scope of the invention defined by 7 the claims following said description:

Referring to said drawings: Figure 1 is a sectional elevation of a coupling involving myinvention, "associated with a shade and j applied to an incandescent, lampsocket, thecoupling being in operative position and a part of the shade being broken away. Fig. 2 is a transverse section on the-line 22 of Fig. 1. Fig. 3 is a. sectional elevation of said coupling in releasing position, a part of the shade being also represented. Fig. tis' a view corresponding practically with Fig. 2, of a different and duplex form of coupling and also shows a globe adapted for connection with this type of coupling. Fig. 5 isa transverse section on the line 5-5 of Fig. 4. Fig. 6 is an elevation of portion of a guard equipped with the coupling, the latter being shown in releasing position. Fig. 7 ,is an elevation of the same guard with the similar J osnPH SACHS, a citiresiding at Hartcoupling in locked relation, of the guard being in section to show a catch. Fig. 8 is a sectional detail view of another form of coupling showing the same in connection with a guard and also applied to a socket. Fig. 9 is a side view of the parts shown inFigL 8, a portion of the head of the guard being broken out. i

Like characters refer to like parts throughout the several views which it will .observed are on different scales.

As already intimated the coupling constituting the-subject matter of the present case can be .utilizedin widely different ways. In

the drawings I have shown several of these. This coupling can be used for detachably connecting hose or pipes or for detachably securing a top or other receptacle, illustrated. Said coupling preferably comprises a clamping member and a toggle for locking the clamping member in clamping relation. Both the clamping member and the toggle may vary radically as to character, depending in a measure upon the nature of the members to be the lower part i cover to a'can, bottle or 7 although none of these isv r separably united.

Ordinarily but not necessarilythe clamping member consists of a plurality of approximately-circular segments, and these segments will embrace preferably or surrounda part; such as the socket of an incandescent lamp. When the toggle connected with the clamping member is in operative or closed position, the clamping member will rigidly and firmly embrace the object in question to an extent sufficient to insure against accidental separation of the parts, although the toggle can be unlocked gomparatively small amount of manual orce.

or opened with a a With the foregoing general.des'cription,

I will now refer first specifically to'Figs. 1, 2 and 3, wherein l nected with a lamp shade or reflector such as that denoted in a general way by 2-, the socket of well-known construction being designated by 3. The shade 2 has an upstanding neck or collar 4 which is intended to embrace the socket 3 and which as shown,

as an interior approximately annular groove or channel 5 to receive the external circular bead or flange 6 of the socket 3 .the coupling isshown conwhen the shade 2 is properly connected with; 2

said socket, whi has-one simple means for interlocking the socket and clamping 1116111,

her. The presence of this groove and bead, however, are not matters of consequence, as

. equivalent means might be substituted therefor or in some cases omitted. \The collar or neck 4 is approximately diametrically opposltely slotted as at 7 to form two du- .plicate segments 8, and this neck or collar 4: I might add constitutes the clamping member of thecoupling shown in Figs. 1, 2

and 3. Although this clamping member 1s. shown as an attached part of the shade 2,

it may be made separably. The segments 8 of the collar 4 near the body of the shade 2 are slit as at 9 thereby producing in said segments a certain amount of resiliency which can be advantageously utilized for facilitating the connection of the clamping member or collar 4 with the socket 3. Although this resilience is naturally of advantage, it is not always essential that it be present as the clamping members of the other forms of the coupling have not this resiliency or at least not so much thereof.

As already indicated-the toggle for lockyoke-like toggle members 10 are bent inward as at 12 to present pivots, and extend freely through perforations in the ends of the segments 8 from the outside thereof. The main or actuating toggle element 11 as represented. is of annular form, and although circular; this is not-imperative, the auxiliary toggle members 10 being preferf bly pivotally connected with the main toggle member 11 interiorly thereof. For example, I may form in the annular toggle member 11 diametrically opposite ears or lugs 13 through perforations in which .the toggle members 10 extend, the connection between said ears and the respective toggle members 10 being approximately midway of the length of the latter. p

In Fig. 3, the socket 3 is shown as having been entered into the split collar 4; the

bead 6 on said socket being nearly in the channel 5. On the sllght farther relative movement, of the collar on the socket saidbead will snap into said channel owing to the resiliency of the collar, during which I action thesegments 8 are slightly spread u open, but the instant that the bead is fully seated in the channel, these segments promptly close upon the bead. In this view end of. the globe" or shade the toggle is open or unlocked, the toggle members 10 extending at an upward, outward angle from their point of connection with the inner terminals of said segments, and the toggle member or ring 11 being up. To lock the collar 4 to the socket the ring 11' is moved downwardly thereby corresponclingly moving the outer ends of the toggle elements 10, so that the centers of the toggle are caused to approach and then cross the dead center line of said toggle, at which point said toggle will be in locked relation to connect the shade 2 securely to the socket 8, it being understood that when the shade is fastened in place the bead 6 is solidly seated in the channel 5. To release the shade the operation described is re versed. It will bg clear that the ring 11 in addition to acting as a member of the duplex toggle also constitutes a facing or finishing ring, inclosing the locking parts and hiding the same from view.

-I have thus far described a coupling which is attached to one object and which is adapted to clamp another object by which said two objects can be separably connected together. I11 Figs. 1 and 5 I show a coupling which has a duplex clamping action being unattached normally to either of the .objects to be joined together. When the sections of the clamping member of said duplex coupling are moved into clamping relation by thelocking mechanism however, said sections will clamp both the objects, and this effect will be obtained by a single movement of said locking mechanism. In the two views in question the coupling is shown as constructed for connecting a glass globe or shade with a socket, although itmight connect any other two parts as already observed. The globe or shade is denoted by 14.- and the clamping member is designated in a general way by 15, said'clamping member 15 being divided to present sections or segments, the upper portion 15 of each being adapted to cooperate with the socket 16, while the lower portion 15 thereof is adapted tocoact with the globe or shade 14. The upper portion 15 of each of the sections or segments of the duplex clamping member 15 is interiorly channeled to receive the customary bead on the socket 16, while the lower portion 15" of each of said sections isv hook-like or in the form of a the bead at the upper claw to engage over 14. The toggle members 17 and the toggle members 18 are like the toggle'members 10 and 11 already described in detail, for which reasonthey requireno further specific descrip tion. With the toggle (composed of the exactly I members17 and 18, open) as shown in Fig.

the socket 16 and shade 14 can both be" 4 'Ilserted in the clamping member 15, and h this is done the toggle member 18 will be drawn downward thereby correspondingly moving the outer portions of the links 17 and causing the sections or segments of the clamping member to approach each other and to clamp against both the shade 14 and the socket 16, it being apparent that when the several centers of the toggle have crossed the dead center line of said toggle, the sections of the clamping member 15, will be firmly clamped to the-shade 14 and socket 16, the beads of the two parts at this time snugly fitting grooves or channels within said clamping member. The clamping member 15, therefore, in addition to being clamped to bothv parts is also interlocked with each, thus insuring double security.

cause the sections or segments Referring now to Figs. 6 and 7 the numeral 19 denotes an incandescent lamp guard which as shown consists of two like sections. In this showing the head 20 of said guard presents a clamping member, being divided as represented to present duplicate sections or segments connected respectively with the companion sections of the guard. To the sections of said head are pivoted exteriorly the yoke-like toggle links 23' and pivoted centrally to these toggle links is the annular toggle member 24, all like the corresponding parts hereinbefore described. When the double toggle is opened or unlocked as shown in rig. 6, the sections or segments of the head 20- are spread soas to receive an incandescent lamp socket which, as will be understood, 1s passed through the ring 24:. WVhen this is done, the toggle is moved to locking position to of said head to closely embrace the socket of the lamp, the head 20 having an interior channel 25 to receive the usual bead on said socket. The guard 19' may, if desired, be equipped with a latch, that shown consisting of a ring 19 at the lower end of one section adapted to receive the half ring 19 at the corresponding end-of the other section.

In the several forms of the device thus Ifar described, the toggle mechanism is in concentric relation with the clamping memher, and the operating element of the toggle mechanism is bodily shift-able, this result being obtained by mounting said operating toggle element for floating moveirent.

Referring now to Figs. 8 and 9 the guard there shown is denoted by 26 and its head is divided or split to present. the segments 27 which jointly constitute a clamping mem her. To the ends of the segments exteriorly thereof are pivoted two pairs of toggle links 28 which unlike the other links are straight or practically so. To the outer ends of the respective pairs oflinks 28 are pivoted the ends f operating toggle -members 29 equipped with upward extensions 30 projecting through slots in the head of the guard 26 and having bent finger pieces 31 to facilitate their operation. To move the time separating the segments 27, so that the head of the guard 26 can receive thesocket. To lock the guard to the socket the finger pieces 31 are depressed, thereby moving the two toggle devices to locked relation and causing the segments 27. to tightly and' firmly embrace the socket.
